Save simulation results to CSV / MAT

[AnHeuermann]

Feature Request

Is there a (simple) way to save the simulation results to a *.csv or *.mat file? I couldn't find one.

I can create a DataFrame and save it myself, but it is very inconvenient. An API function would be very nice.

My Workaround

using FMI
using DataFrames
using CSV

outputVars = ["outputs[1]", "outputs[2]", "outputs[3]", "outputs[4]", "outputs[5]", "outputs[6]", "outputs[7]", "outputs[8]"]
result = fmiSimulate(fmu, 0.0, 10.0; recordValues=outputVars)

df = DataFrame(time = result.values.t)
for i in 1:length(result.values.saveval[1])
  df[!, Symbol(names[i])] = [val[i] for val in result.values.saveval]
end
CSV.write(resultFile, df)

We could add this as weak dependency using Requires.jl.
There is already a command fmiSaveSolution, we could make a "dispatch" for file formats other than JLD2 (only if MAT.jl or CSV.jl is imported).

I will add this soon.

@ThummeTo should I handle this or is it of rather low priority?

Julia 1.9 can now handle package extensions similar to Requires.jl:
